Solar panels are devices that convert sunlight into electricity. They are made up of many small units called solar cells, usually made from silicon — a material that can absorb sunlight and release electrons, creating an electric current.
Each panel generates direct current (DC) electricity, which is then converted into alternating current (AC) by an inverter, making it usable for homes, schools, businesses, and industries.
Solar panels are usually mounted on rooftops, ground structures, or even portable frames, depending on the application. They work best when placed where they can receive direct sunlight for most of the day.

Requirements for Solar Panel Installation
Before installing a solar energy system, several technical, physical, and safety requirements must be met to ensure efficient performance and long-term reliability.
🏠 1. Site Requirements
-
Adequate Sunlight: The location should receive at least 4–6 hours of direct sunlight per day.
-
Proper Roof Orientation: In the Northern Hemisphere, roofs facing south are ideal for maximum sunlight exposure.
-
Roof Strength and Condition: The roof must be strong enough to support the weight of the panels and mounting structures.
-
No Shading: Ensure there are no tall trees, buildings, or poles casting shadows on the panels.
🔋 2. Electrical Requirements
-
Inverter: Converts the DC power from solar panels to AC power used in homes.
-
Batteries (optional): For storing energy for use at night or during power outages.
-
Charge Controller: Regulates voltage and current to prevent battery overcharging.
-
Cables and Connectors: Use high-quality solar-rated wires and connectors (MC4 type).
-
Circuit Breakers and Fuses: For safety and protection against electrical faults.
🧰 3. Equipment Requirements
-
Solar panels (monocrystalline, polycrystalline, or thin-film).
-
Mounting structure (roof or ground mount).
-
Bolts, brackets, and clamps for securing panels.
-
Tools such as drills, spanners, and multimeters.
-
Safety gear — gloves, helmet, harness, and non-slip shoes.
🧠 4. Technical Requirements
-
System Design: Calculate the total power needed (in kW) and the number of panels required.
-
Tilt Angle: The panel’s angle should match the latitude of the installation site for maximum efficiency.
-
Wiring Configuration: Choose between series or parallel connections based on voltage and current needs.
-
Qualified Installer: Use a certified solar technician to ensure safety and compliance with electrical standards.
🛡️ 5. Legal and Regulatory Requirements
-
Obtain permits or approval from local authorities (if required).
-
Ensure the system meets national electrical codes and safety standards.
-
If connecting to the grid, contact the utility company for inspection and authorization.
